ADUM3190ARQZ-RL7 from Analog Devices, in a QSOP-16-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD1 | power_in | Primary-side main supply voltage input, operating range 3.0 V to 20 V, requires 1 μF bypass capacitor to GND1. |
| 2 | GND1 | power_in | Primary-side ground reference. |
| 3 | VREG1 | power_out | Primary-side internal regulated supply output approximately 3.0 V, requires 1 μF bypass capacitor to GND1. |
| 4 | REFOUT1 | output | Primary-side precision reference output 1.225 V ±1% over −40°C to +125°C temperature range, maximum load capacitance 15 pF. |
| 5 | NC | unconnected | No connection pin; must be connected to GND1 to prevent floating node. |
| 6 | EAOUT2 | tri_state | Open-drain isolated output voltage 2 with 2.6 V/V gain, delivers ±1 mA maximum current, requires external pull-up resistor to VDD1. |
| 7 | EAOUT | output | Isolated error amplifier output delivering ±3 mA with voltage swing from 0.4 V to 2.7 V. |
| 8 | GND1 | power_in | Primary-side ground reference. |
| 9 | GND2 | power_in | Secondary-side ground reference. |
| 10 | COMP | output | Primary-side operational amplifier output driving feedback control through isolation barrier, connection point for external compensation network. |
| 11 | −IN | input | Inverting input of primary-side op-amp, connection point for power supply output voltage divider and external compensation network. |
| 12 | +IN | input | Noninverting input of primary-side op-amp, typically connected to 1.225 V internal reference or external signal input. |
| 13 | REFOUT | output | Secondary-side precision reference output 1.225 V ±1% over −40°C to +125°C temperature range, maximum load capacitance 15 pF. |
| 14 | VREG2 | power_out | Secondary-side internal regulated supply output approximately 3.0 V, requires 1 μF bypass capacitor to GND2. |
| 15 | GND2 | power_in | Secondary-side ground reference. |
| 16 | VDD2 | power_in | Secondary-side main supply voltage input, operating range 3.0 V to 20 V, requires 1 μF bypass capacitor to GND2. |
